Tammemagi (2009, p.197) claims that “Renewable energy sources–such as windmills, solar panels, and hydro-electric generators, which produce no greenhouse gases–are an excellent way of combating global warming. The use of wind power, a seemingly simple and benign energy source, has increased rapidly in recent years as wind turbine technology. From 2000 to 2007, worldwide wind-power generating capacity increased from 18.000 MW to 92,000 MW, a five-fold increase. The world leader in wind power is Germany, followed by the United States, Spain, India, and Denmark. Denmark produces almost half of its electricity from wind.“
